Resumen

This paper analyzes a procedure to determine the solar potential through solar radiation estimation models based on climatic parameters, applying them at a local level, where there are no measurement records. The study was carried out in the district of San Mateo, province of Huarochirí, in the highlands of the Lima region, Peru. The use of three estimation models was proposed as calculation alternatives, based on air temperature, since this variable is measured in the vast majority of automatic stations. The use of these models responds to the relationship between temperature and radiation and its practical application, including attenuation due to atmospheric effects. The models used were Bristow-Campbell, Hargreaves-Samani and Annandale, of which the Bristow-Campbell model was selected, which showed better results compared to its peers, obtaining an R2 of 0.818, RMSE of 1.14, MBE of 0.06 unlike of the R2 of 0.921 and 0.921, RMSE of 1.27 and 1.27, MBE of-0.52 and-0.52 of Hargreaves-Samani and Annandale respectively. To develop the models, a 10-month time series was recorded from its own automatic weather station, complementing the information with a 9-year record of historical data extracted from the free NASA application (POWER) for the auxiliary measurement points located in the whole district. The NASA data were validated by correlating them with the data obtained on the ground giving acceptable results for their application. This made it possible to generate a data log mesh with the measurement points in order to perform the simulation in the free QGIS software and obtain the radiation distribution maps. The annual average radiation was 5.26 kWh/m2 day, which is highly profitable. It is considered that the methodology developed in this research is applicable to estimate the distribution of incident solar radiation at the local level, always considering the conditions of the study area. The global solar radiation values produced in this thesis can be used in the design and performance calculation of solar applications for the San Mateo district. © Roman Science Publications Ins.
